Sebastien Vettel testing Infiniti's production Etherea?

It sounds like Sebastian Vettel has had his hands full recently, juggling his Formula One racing career while moonlighting as the newly appointed director of performance at Infiniti. On that latter note, Autocar is reporting that Vettel has been testing a production version of the Etherea Concept at France's Circuit Paul Ricard.
There is still no word as to when we could see this car go into production or what it will be called (possibly the Q30), but it will likely share a platform with the Mercedes-Benz A-Class as a part of the Daimler/Renault-Nissan collaboration. The article also said that this future entry-level Infiniti would be produced at Nissan's Sunderland, UK plant.

Nissan GT-R convertible offered in three flavors from NCE

Newport Convertible Engineering, the Southern California company that can't keep its top on, has revealed on its website that it is now producing three different droptop versions of the Nissan GT-R Convertible. It's just another page in its work with high-end offerings like the new Range Rover and the Jaguar XJ. NCE owner Al Zadeh tells Autoblog that the superfast speedster came about during a trip to Abu Dhabi, when clients of his that collectively owned ten GT-Rs said they wanted him to engineer a convertible. They didn't want to see pictures, though, "They wanted to touch it and see it," he said.
So he built a convertible with a traditional, unadorned soft tonneau cover (the white one in our gallery) and another with hard tonneau cover fitted with roll hoops and a low-rise dual cowl (the blue one). When the clients saw it, "They said they wanted something more glamorous," Zadeh said. So he came up with the black version above with a hard tonneau cover and can't-miss-it cowling that, frankly, looks pretty good to us in that color and with those wheels.
Clients satisfied, the order books have opened for other GT-R owners around the world. The most restrained version runs $29,500 to build, the other two retail for $49,000, and all of them require a donor GT-R and eight weeks to finish. With facilities in SoCal, Europe and the Middle East, you won't even have to send your Godzilla too far away if this is the look you've decided it just has to have.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
